Scientists Publish Largest-Ever Study on the Genetics of Modern Africans

When scientific research is published, the authors often confess that they wish they'd collected more data. Critical reviews of research studies often say the same thing. Indeed, if there's anything scientists love, it's more data. Which is why the members of an international team of genetic ...

New 23andMe Lab Searches Genome for Native American Ancestry

Every family has its legends. Maybe it's a story about how they're descended from a passenger on the Mayflower, a Confederate soldier or Charlemagne. Of all the classic American family legends, stories of a Native American ancestor are among of the most common. Many times there's a well-documented link ...

Three New Surveys from 23andWe Ask New Kinds of Questions

Since 23andWe debuted in May, we've asked our customers about all sorts of things: their hair color, earwax consistency, whether they tend to look on life's bright side. Sometimes people have been surprised to learn that something like your susceptibility to motion sickness — or even which way the hair swirls ...

Study of Breast Cancer among Latinas Shows Importance of Ancestry in Disease

People sometimes think of ancestry as the "fun" part of the 23andMe Personal Genome Service™, an intriguing glimpse at the past that is completely unrelated to our more serious Health and Traits features. But a new paper shows how ancestry can actually reveal quite a bit about the genetics of disease. In ...

African American Roots: What Genetics Can Reveal

Because their ancestors often were slaves during the 18th and 19th centuries, and therefore usually lacked birth or death certificates, it is very difficult for African American genealogists to trace their ancestors further than a few generations. Even when they can trace their ancestry to the slavery era, it ...

A Different Kind of Gene Mapping: Comparing Genetic and Geographic Structure in Europe

By Chris Gignoux and Mike Macpherson It should be no surprise that in general, we are more genetically similar to our neighbors than to people living far away. The reason is fairly simple — until recently in human history it was fairly rare for people from widely separated geographic regions to even meet, ...

Did Neanderthals and Humans Mate? The Answer, Again, is No

(Ed: Newer research suggests that Homo sapiens and Neanderthals did in fact interbreed. On average, two to four percent of DNA in present-day humans who trace their ancestry from Europe or Asia comes from our Neanderthal cousins. 23andMe customers can check out their own Neanderthal ancestry here! -- ...

The Origin of Farming in Europe: A View from the Y Chromosome

This guest post is by Roy King, who is a professor of psychiatry at Stanford University and a research colleague of Stanford geneticist and 23andMe scientific adviser Peter Underhill. Roy and Peter have been using genetics to trace the spread of agriculture from the Near East to Europe. The question of ...
